Gearbox for mashimas

[uax6]

I’ve aquired some kits recently, and although they are badly built, they have what look like almost new mashima open frame motors. I usually use cans, but I have two identical motors, and convinently two indentical kits to put them in. I’ve never had much luck meshing gears without gearboxes, so was wondering if there was a gearbox that can mount to theses motors. They are of an old pattern with no mounting screws on the end, just one underneath. 

 

 

They also appear to have about 1mm of endfloat, which I presume is normal for these motors.

 

TIA

I've never seen a Mashima that looks like that - they must be pretty old. Since the ends are brass I reckon you could fit just about any Branchlines or High Level gearbox by attaching it with low melt solder, such as 145 - clean it up, nice hot iron, and just a quick dab each side. The centre boss looks quite hefty and you'd probably have to open up the hole in the gearbox a bit. Big shaft too, hopefully 2mm but worth checking it's not imperial, although I believe adapter sleeves are available.

It looks like an Anchorage D13 motor marketed by MG Sharp during the 1980s.  The Craftsman & DJH loco kits were designed around Anchorage motors.

 

The motors were usually used with Romford single stage gears, sometimes with an etched or lost wax gear cradle https://www.worthpoint.com/worthopedia/mashima-d13-motor-e-finecast-motor-753578909 

 

I am reasonably certain I have some suitable gearboxes for your motor.

 

I will post an update when I check my spare parts box.

I am certain that Southeastern Finecast do motor mounts for these motors

 

This may be the one, give Dave a call on Monday  Tel 01342 82 4711

Info on SEFinecast mount

The one you are showing is the Finecast X04 replacement motor mount, which is totally different to the etched D13 motor mount I commented on, the former being designed to fit into Hornby chassis and the latter into kit chassis. On the second hand market Perseverance and Alan Gibson both did them on much the same design as SEF

That’s all I could find on their website: but the plate that makes it into an X04 replacement looks to be optional, so it might work.

Thought it might be a helpful link. Obviously not.

Was helpful (especially for anyone looking for a replacement for an X04 in a Hornby rtr chassis) but the etched motor mount has axle holes in it to assist in meshing the gears. Pity the SEF website does not show photos of all its products, but they are model makers not IT specialists

 

Thanks

One thing to watch out with these D11/13's is that only one side of the brushes are insulated so if you want an electrically 'dead' chassis you must isolate them from it somehow. The DS10/D11/D13/TA12 were first imported by MG Sharp when such as the XO4/MW5 reigned supreme and Sagami's were the other option around. IMHO all except the 16x30mm TA12 cans had rather high rpm's and lack of real grunt.

A general problem. Not sure that great specialisation is required, but the IT world moves do quickly.

That was (is?) a superb motor. I rather liked the round 1620 (not the 1420 “flat can”), and wish I had bought a load when their withdrawal was announced, although not as much as I wish I had half a dozen of the Exactoscle milled brass gearboxes. (Have since bought some nice coreless motors instead of the 1620s.)

I would agree with Simon's comments on the D13 motor, they were considered to be a superior motor with a lower rpm and a higher torque than the similar though shorter D11 motor. 

 

A Mike Sharman milled brass gearbox would be an alternative if you are unable to source a suitable gear cradle.

 

The photo is of one of the original batch of Sharman boxes which had helical gearing.
